Vendor registration/maintenance

Welcome to the County of Riverside Vendor registration portal


We are implementing a new and modern electronic procurement system which will ultimately become your one-stop shop for doing business with the County of Riverside.  Part of our new system is a dynamic vendor portal, which will provide several new features to the county's vendor community.  The new features include the ability to:

  • Maintain a profile of your critical business information
  • Add and update business information when changes occur
  • Upload insurance and diversity certifications
  • View and participate in competitive bids
  • View invoice payment status and history
  • View order status and history
  • Submit electronic invoices directly to the County of Riverside

To get started you will need to go through a quick registration process in order to open up these features to you and get you on your way to doing business with the county. 

Registering as a County of Riverside vendor is required.  However, it is free, easy and only takes a few minutes to join.  By selecting the RivcoPRO link below, you will be routed to a secure website to complete the registration process.  Upon successful completion of your registration you will have access to your secure portal where you can add additional detail about your organization, invite colleagues within your company to become users, and more.

Public Purchase


While RivcoPRO will ultimately become the county’s sole vendor portal, the county will continue utilizing the services of Public Purchase, a third-party electronic bidding software until the system is rolled out across all county departments.  Please create and maintain a Public Purchase profile until notified otherwise.  This will ensure your organization does not miss bid postings in either system during the transition. 


There is NO CHARGE to register and utilize this service for the County of Riverside.  Public Purchase has other services available for a fee, but that is solely at your discretion and not required to do business with the County of Riverside.


To get started, click on the Public Purchase link below.
